What It Helps Address

• Cracked or leaking coolant reservoir housing
• Faulty reservoir sensor mounting or sensor-related tank replacement needs
• Loss of coolant from an aging expansion tank
• Cooling system service after reservoir damage or discoloration
• Replacement of a reservoir that no longer matches OE fitment

Installation Notes

Verify the vehicle’s OE number, sensor configuration, and cap requirement before installation. This reservoir is listed without a cap, so reuse or source the correct cap separately if needed. Confirm the mounting location and physical dimensions against the removed part before filling and bleeding the cooling system.
